Answer:
0.15 m/s² east
Explanation:
We can use following kinematic equation for Uniformly-Accelerated Motion to solve this problem:
<h3>v = v₀ + a × t</h3>Where <em>v</em> is the final velocity, <em>v₀ </em>is the initial velocity, <em>a</em> is the acceleration and <em>t </em>is the time interval.
<u>The data of the problem is:</u>
- v₀ = - 100km/h (remember to have a frame of reference, I decided traveling west will be towards the negative values and traveling east will be positive).
- v = 0 km/h (the car comes to a full stop)
- t = 3 min
<u>Replacing the data in the formula</u>:
0 km/h = -100 km/h + a × 3 min
It's very important to use the same units when solving problems. I will convert kilometer to meters and hour or minutes to seconds, because the answer choices are given in m/s².
- 0 km/h = 0 m/s
Then:
And considering our frame of reference, a positive sign indicates that the acceleration is east-bound.
